Personalized radiotherapy treatment planning based on functional imaging

In recent years, a huge progress in the field of radiotherapy could be observed. From treating patients with kilo-voltage X-rays units to cutting edge technology that can deliver a certain dose with an extreme precision. Modern radiotherapy is characterized, among others, by an individualized approach to the patient. This can be provided by functional imaging which is another step toward a better tumor control. In this paper, we discuss the potential application of functional imaging modalities in personalized radiotherapy planning with emphasis on dose painting. Some limitations of this approach will also be evaluated.
